Hi, I'm Anshuman Fire Phoenix

CS Undergrad at IIIT Kottayam & Lead, App Development Subclub at BetaLabs.

Previously AI Engineering Intern, building multi-agent analytics frameworks in LangGraph, production LLM evaluation pipelines, and observability infrastructure.

I enjoy building agentic AI infrastructure, distributed systems, and storage engines β€” exploring how systems work under the hood, from low-level LSM tree internals to real-time event streaming pipelines.

⚑ What I Work On

  • AI & Agent Infrastructure: LangGraph, LangChain, DeepAgents, supervisor agent orchestration, evaluation harnesses, deterministic tool execution
  • Distributed Systems & Concurrency: Multithreading, atomic primitives, race condition diagnosis, distributed locking, idempotency guarantees
  • Storage Engine Internals & Data Engineering: LSM Trees (WAL, MemTable, SSTables, Bloom Filters), write amplification trade-offs, Change Data Capture (CDC), zero-loss replication
  • High-Performance Backend & Networking: FastAPI, REST APIs, WebSockets, connection pooling, backpressure handling, rate limiting
  • Reliability & System Design: Circuit breakers, exponential backoff with jitter, dead-letter queues (DLQ), telemetry, p95/p99 latency profiling

πŸš€ Featured Projects

Enterprise CDC Streaming Pipeline

C++17 Kafka Debezium PostgreSQL Redis Elasticsearch Docker

  • Real-time WAL change data capture ingesting 1,000+ req/s with zero data loss across 216k+ soak events.
  • High-throughput C++ consumer workers with manual offsets, exponential retries, and DLQ poison message isolation.
  • Atomic Lua-scripted LSN monotonicity guards in Redis ensuring sub-millisecond cache consistency.

🌐 Open Source Contributions

Core Developer Infrastructure & Release Tooling

PR #8379 CI Passed Python

  • Refactored developer release pipeline architecture and relative path hierarchies to standardize dev onboarding across the core repository.
  • Completed Google CLA verification and collaborated directly with Google Quantum AI software engineers (Michael Hucka, Pavol Juhas) through code review to immediate merge.

Quantum Algorithms & Compiler Benchmarking (MQT Bench)

PR #1037 Qiskit CI

  • Engineered scalable Superdense Coding communication benchmark (Bennett & Wiesner, 1992) to evaluate circuit compilation and entanglement distribution across modular Bell pairs.
  • Diagnosed and resolved a Qiskit 2.5+ target-independent compiler optimization anomaly where commutation passes collapsed entangling CX gates; introduced pair-local barriers to guarantee protocol workload retention.
  • Constructed end-to-end regression suites with StatevectorSampler verifying full fidelity across all 2-bit permutations, actively triaged with TUM maintainers (Dr. Lukas Burgholzer, Simon Hofmann).

Agent Capability Authorization & Testing Infrastructure

PR #716 CI Passed CrewAI

  • Engineered the official quickstart architecture and test suite for the CrewAI GuardedCrew builder, enforcing role-based tool policies, argument regex constraints, and strict post-kickoff audit detection.
  • Implemented an offline deterministic LLM double to run reproducible test runs without provider API keys; established cross-version compatibility across CrewAI 1.5–1.15 in the CI matrix.

Security Hardening & Log Sanitization Infrastructure

PR #1308 CI Passed MCP

  • Mitigated log injection vulnerabilities across configuration modules by migrating eager f-strings to lazy parameterized logging (%-formatting).
  • Enforced static security boundaries by integrating configuration layers into GUARDED_MODULES regression suites.

βš™οΈ Core Engineering & System Design

  • Concurrency & Thread Safety: Mutexes, condition variables, lock contention analysis, atomic operations, race-condition mitigation, and memory lifecycle management.
  • Distributed Reliability & Fault Tolerance: Idempotent message consumers, distributed rate-limiting (Token Bucket / Leaky Bucket), retry storm protection with exponential backoff & jitter, and Dead-Letter Queue (DLQ) patterns.
